近几年来,在重庆市各区县城镇建设中处理软弱地基时,较广泛地采用了钻孔灌注桩基础。据了解,由于各家对工业与民用建筑灌注桩基础设计与施工规程(JGJ4-80,以下简称“规程”)的理解掌握不一,即使在相同地质条件下,各家用“规程”经验公式确定的单桩地基承载力也相差甚多。为此,笔者对支承于基岩面或嵌入基岩内的钻
In recent years, borehole pile foundations have been widely used in the treatment of soft foundations in urban construction in various districts and counties in Chongqing. It is understood that due to various understandings of the design and construction regulations for the foundations of industrial and civil construction piles (JGJ4-80, hereinafter referred to as “procedures”), even under the same geological conditions, each household “procedure ”The bearing capacity of a single pile determined by the empirical formula is also very different. For this purpose, the author drilled on a bedrock surface or embedded in bedrock.
